HI Cecilie Nordbø
inside need dataSource()
--------------------------
if (!IsPostBack)
            {
                  grdClassSchList.MasterTableView.FilterExpression = "([EducationPeriodName] LIKE \'%" + " Year 2010-2011" + "%\') ";

                    GridColumn column = grdClassSchList.MasterTableView.GetColumnSafe("EducationPeriodName");
                    column.CurrentFilterFunction = GridKnownFunction.Contains;
                    column.CurrentFilterValue = "Year 2010-2011";
            }
----------------------------
column Name = "EducationPeriodName"
Filter value = "Year 2010-2011"

and Set this Property for Grid : EnableLinqExpressions="false"
